Know before you buy
Yes, Oregonism XL is formulated as a super-soluble powder, making it safe for use in hydroponic reservoirs and irrigation systems without causing clogs.
No, it is specifically designed to be tolerant of heavy feeding programs. It works alongside your current nutrients to improve uptake rather than competing with them.
The VAM fungi increase root surface area for better nutrient absorption, while the Bacillus and Pseudomonas bacteria help break down nutrients into more available forms, ultimately strengthening the plant's resistance to stress.
Absolutely. It is highly effective in potting soil, coco coir, and hydroponic setups, helping to establish a robust root zone in any growing medium.
By expanding the root system and improving the plant's overall metabolic efficiency, the microbial blend helps plants maintain hydration and vigor even when water availability fluctuates.
